loke

Etymology

The word came into English as Middle English loke, which developed from Old English loca ("a bar, bolt; enclosure, stronghold"), itself from Proto-Germanic *lukô, *lukǭ ("lock, clasp, shutter, opening"), and ultimately from Proto-Indo-European *lewg- ("to bend, turn"). It is a cognate of Icelandic loka ("clasp, latch, lock, bolt"). See also lock.
